Trichothecene mycotoxins 2types

Trichothecene mycotoxins are fungal toxins, or mycotoxins, produced by fungi that grow on grains, such as wheat. KM assay center determines whether and which of two types of trichothecene mycotoxins, namely DON, NIV, are present in the sample using an ELISA* method developed by Kyowa Medex Co., LTD.

＊Enzyme-Linked ImmunoSorbent Assay

Deoxynivalenol（DON)

Deoxynivalenol is a toxin produced mainly by the Fusarium fungi. If ingested in large quantities, DON can induce symptoms of poisoning, such as nausea, vomiting and diarrhea.

The ministry of Health, Labour and Welfare set the provisional standard value for the level of DON found in wheat in the administrative guideline in 2002 at 1,100ppb (parts per billion) and gave notice of this standard to the concerned parties.

Nivalenol (NIV)

As with DON, nivalenol is a toxin produced mainly by the Fusarium fungi. If ingested in large quantities, NIV can induce symptoms of poisoning, such as nausea, vomiting and diarrhea. Although there is no established standard value for NIV, NIV exhibits toxicity that is similar to or greater than that with DON. Domestically, NIV contamination is observed in western Japan from time to time.
